Slope Percentage Formula:
| From: | To: |
Slope percentage is a way to express the steepness of a slope as a percentage. It represents the ratio of vertical rise to horizontal run multiplied by 100. This measurement is commonly used in construction, landscaping, and civil engineering in the UK.
The calculator uses the slope percentage formula:
Where:
Explanation: The formula calculates what percentage the vertical rise is of the horizontal run. For example, a 1 meter rise over a 10 meter run would be a 10% slope.
Details: Calculating slope percentage is crucial for proper drainage planning, accessibility compliance, construction safety, and landscaping projects. In the UK, building regulations often specify maximum slope percentages for various applications.
Tips: Enter both rise and run values in meters. Both values must be positive numbers. The calculator will automatically compute the slope percentage.
Q1: How is slope percentage different from slope angle?
A: Slope percentage is a ratio expressed as a percentage, while slope angle is measured in degrees. They are related but represent the slope differently.
Q2: What is considered a steep slope in the UK?
A: In UK construction, slopes above 10% are generally considered steep, with special considerations needed above 25%.
Q3: How do I measure rise and run in the field?
A: Use a level and measuring tape, or specialized surveying equipment for more precise measurements.
Q4: Can I use different units for rise and run?
A: The units must be the same for both rise and run (both in meters or both in feet). This calculator uses meters.
Q5: What's the maximum recommended slope for wheelchair access?
A: UK accessibility guidelines recommend no more than 5% slope for wheelchair routes, with 8.33% (1:12) as the absolute maximum for short distances.
